This was about a half a second worth of clip, so I had to rewind it to get the screen cap (and even realize what I was looking at), but the movie trailer for "Spare Parts" has an old Gen 1 GMC or Chevy Suburban-style panel truck in there. Rusty as all ****, and it's been scavenged for parts...but she's there.
I thought you guys would appreciate it. Now that I'm looking, it's most likely a Chevy if it's more-or-less original -- 5 lugs on the wheels.
